Nelson targeted by hackers

Sen. Bill Nelson, D-Fla., a member of the Intelligence Committee and a panel that oversees NASA, said Friday that his office's computer network has been attacked by someone in China.

Nelson said the network has been hacked into three times in the past 30 days but no classified material was obtained.

The attacks targeted computers used by a foreign-policy aide, a former NASA adviser and the deputy legislative director, he said in a statement.

Nelson said he'll work with Sen. Jay Rockefeller, D-W.Va., who chairs the Senate Commerce, Science and Transportation Committee, and Sen. Olympia Snowe, R-Maine, on cybersecurity legislation they are proposing. It would create a position for coordinating national computer-security strategy, require assessments of vulnerability and share information on potential breaches.
